c类型的结构体转成c#的结构体，请大神指导。。。

[skl_1]

1、如下是C类型的结构体：

typedef unsigned char MUInt8;

typedef signed int MInt32;

typedef unsigned int MUInt32;

typedef void* FaceEngine;

typedef MLong MRESULT;


/*Define the image format space*/
typedef struct __tag_OFFSCREEN
{
MUInt32 u32PixelArrayFormat;
MInt32 i32Width;
MInt32 i32Height;
MUInt8* ppu8Plane[4];
MInt32 pi32Pitch[4];
} OFFSCREEN, *LPOFFSCREEN;

/*Define the rect */
typedef struct __tag_rect
{
MInt32 left;
MInt32 top;
MInt32 right;
MInt32 bottom;
} MRECT, *PMRECT;

/*Define the face result*/
typedef struct __tag_FaceResult
{
int nface_;
MRECT *rcface_;
float *score_;
} FaceResult, *PFaceResult;

请问下 OFFSCREEN 、FaceResult这几个结构体翻译成 C#格式 的结构体是怎么样的？



2、请问下几个API如何转换成C#的接口？

AFD_API MRESULT AFD_Initial(FaceEngine *face_engine, const int max_face_num = 10, const int nscale = 16,
const float threshold = 0.7f, const int enable_tracking = 0, const int device_id = 0);

AFD_API MRESULT AFD_Detect(FaceEngine face_engine, const OFFSCREEN & img, FaceResult **face_res,
const MRECT *roi_rect = NULL, const int roi_num = 0);

AFD_API void AFD_Release(FaceEngine face_engine);


请大神指教，谢谢!

typedef定义了原类型，根据元类型转换成c#类型，对应关系不明确的可以网上查

[Milo米啊米啊米]

把你自己定义的类型替换成对应的类型就可以了，下面是个例子 http://www.cnblogs.com/HuangWj/p/5633675.html

下面是我转换的结构体和接口，大神们帮忙看看对不对。。

/*Define the rect*/    
        public struct MRECT
        {
             int left;
             int top;
             int right;
             int bottom;
        } 

         public struct MPOINT
        { 
            int x; 
            int y; 
        } 


/*Define the image format space*/    
        [StructLayout(LayoutKind.Sequential)]
        public struct OFFSCREEN
        {
            uint  u32P下ixelArrayFormat;
            int  i32Width;
            int  i32Height;
            [MarshalAs(UnmanagedType.ByValArray, SizeConst = 4)]  
            string[] ppu8Plane;
            [MarshalAs(UnmanagedType.ByValArray, SizeConst = 4)] 
            uint[]  pi32Pitch;
        };

/*Define the face result*/    
        public struct FaceResult 
        {
            public int nface_;
            public MRECT *rcface_;
            public float *score_; 
        };

接口：

        [DllImport(@"\ArcsoftSDK\arcsoft_face_detection.dll", EntryPoint = "AFD_Initial", CallingConvention = CallingConvention.StdCall)]
        public static extern int AFD_Initial(ref FaceEngine face_engine, int max_face_num = 10, int nscale = 16, float threshold = 0.7f, int enable_tracking = 0, int device_id = 0);


        [DllImport(@"\ArcsoftSDK\arcsoft_face_detection.dll", EntryPoint = "AFD_Detect", CallingConvention = CallingConvention.StdCall)]
        public static extern int AFD_Detect(FaceEngine face_engine, ref OFFSCREEN img, ref FaceResult face_res, MRECT roi_rect = NULL, int roi_num = 0);


        [DllImport(@"\ArcsoftSDK\arcsoft_face_detection.dll", EntryPoint = "AFD_Release", CallingConvention = CallingConvention.StdCall)]
        public static extern void AFD_Release(FaceEngine face_engine);
